Answer:
- domain: all real numbers
- range: y ≥ 0
Explanation:
The domain is the horizontal extent of the graph. For a graph like this, we assume the ends extend to infinity, both horizontally and vertically. Then the horizontal extent (domain) is from -infinity to +infinity: all real numbers.
The graph does not go below y=0, so the vertical extent (range) is y ≥ 0.
